The lost mafia princess

The Giovanni's are the Italian Mafia. It is the most powerful mafia. For 8 generations the family have been trying to have a princess in the family but have been unsuccessful. That is until Alina Giovanni and her twin Adrian were born. Due to Alina being born she was target for the other mafia's especially the Russians who hated the Italians due to their success. Alina is taken by them and brought up in terrible conditions. The whole family was heartbroken but never gave up trying to find her. With 6 brothers and parents never forgetting her they were sure to get her back. They weren't the most powerful mafia for nothing.

How long do you think it would take to get her back and make the family whole again, if that was even possible? Would things turn out ok in the end?
